run

void run(int type,
 byte @Nullable [] message)

Emitted when we receive a message from the peer.

As a convenience, the message data will always be null-terminated, but the NUL byte will not be included in the length count.

upcall

default void upcall(MemorySegment sourceWebsocketConnection,
 int type,
 MemorySegment message)

The upcall method is called from native code. The parameters are marshaled and run(int, byte[]) is executed.
